ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 533347, dated February5, 1895.

Application filed May 17, 1894: Serial No. 611,558. (No model.)

To aZZ whom, it may concern.-

Be itknown that I, JOHN G. DOUTY, of Williamsport, in the county ofLycoming and State of Pennsylvania, have invented certain 5 new anduseful Improvements in Electric Railways; and I do hereby declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to animprovement in underground electric railways,the object of the invention being to reduce expense of construction to aminimum; to facilitate repairs 1 and altogether to provide a substantialconstruction and one which, although underground, will be easilyaccessible for repairs and which shall be effectual in all respects inthe performance ofits functions.

Vi ith these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure l is a view in cross sectionthrough the road bed and a portion of a car traveling on the railsthereof. Fig. 2 is a detail view illustrating I the trolley arm and slotcleaners. 'Fig. 3 is a view in perspective of a portion of two railsshowing how they are electrically connected Fig. 4: is a detached viewshowing the trolley arm and wheel and the tubular arm.

A, A, represent the rails of the track.

3 5 These rails are secured to cross ties 1, located below the surfacefar enough so that the treads of the rails will be about flush with thesurface of the road bed. The cross ties 1 in turn are supported onlongitudinal stringers 2 located directly beneath the rails in the usualmanner, and these ties and stringers are embedded in the earth, inmasonry, hydraulic cement or other suitable substructure adequate forthe purpose of effecting a solid and 4 5 substantial foundation. Therails themselves may of course be of any pattern and preferably thetread is of considerable width as shown for the reason that the inneredge of this tread is utilized as one of the slot irons, the

slot through which the trolley arm passes, not

being located midway between rails as is customary, but next to therails at one side of the track for various reasons. The reasons arethese: One slot iron may be dispensed with altogether as the rails atone side of the 5 5 road bed serve the double purpose of rail and slotiron, thus reducing expense of construction greatly. Again itfacilitates in the turning of curves as it brings the trolley arm nearthe wheels on one side of the car.

Chairs B are secured at intervals, to the cross ties 1 and in proximityto the rail A at one side of the road bed, the space between forming theslot 3 for the trolley arm. The chairs B are furnished at the top withan outwardly projecting, horizontal flange 4: which forms seats orsnpportsfor the guard rail or slot iron 0. The latter consistspreferably of a horizontal cap 5 secured to flanges 4 of the chairs andapair of depending flanges 6 and 7 which fit around and incase the upperends of the chairs, the inn er one 6, extending downward far enough toform a guard for the trolley wire or conductor D, which latter iscarried in the space between this flange 6 and 7 5 the chair, and theother flange 7 bolted or otherwise secured to the chair, so that ifoccasion requires it, this slotiron may be readily removed or repaired.

The trolley wire D is supported by suitable 8o insulators 8, from theflanges 4 of the chairs B and it may be braced laterally by rods orwires 9, extending from the insulators in either direction to theflanges 6 and 7.

To the truck of the car a frame or bracket E is secured at any desiredpoint between the car wheels, and projects a short distance inwardly. Tothe truck and the cross bar 10 of the frame or bracket E, journal boxes11 are secured and adapted to receive two arms 0 or trunnions 12projecting laterally from a tubular arm or socket piece F. Springs 13are located on the arms or trunnicns 1:2 and bear at their respectiveends against the journal boxes 11 and the tubular arm or socket 5 pieceF, whereby to permit a yielding lateral movement of the latter.

A trolley arm G passes loosely through the tubular arm or socket piece Fand is adapted to turn freely therein, the upper end of said roe trolleyarm being adapted to project within the car, where it is connected withany suitable devices for manually moving it vertically to remove trolleywheel H, carried by the lower end of the arm G, out of contact with theconductor or trolley wire D. A spindle 14: is secured to and projectslaterally from the lower end of the flattened portion 14 of" the trolleyarm G, for the accommodation of the trolley wheel II. On this spindle asleeve 15 of hard rubber is secured and extends from end to end thereof.The outer end of the sleeve 15 is somewhat contracted in size and onthis contracted portion a collar 16, preferably of brass, is secured andon the brass collar the trolley Wheel is revolubly mounted. An arm 17projects from the brass collar 16, parallel with one face of the trolleywheel and is made with a socket for the reception of a conductor 18,held therein by means of a suitable set screw 19. From its connectionwith the brass collar 16, the conductor 18 will be passed through a pipe23, preferably of lead, secured in a groove in the edge of the lowerportion of the trolley arm and thence to the motor on the car. Aninsulated disk 20 is placed on the end of the spindle l4. and bearsagainst the trolley wheel, being retained in position by means of asuitable nut 21. Lateral movement of the trolley wheel toward thetrolley arm will be prevented by the sleeve 15,, the shoulder 22 ofwhich bears against the brass collar 16.

The trolley arm G is provided with a fixed collar 24 adapted to bearnormally against the shoulder 25 at the upper end of the tubular arm orsocket piece F, the lower end of which latter is internally screwthreaded for the reception of a hollow nut 26, through which saidtrolley arm passes. On the trolley arm, between the collar 24 and thehollow nut 26, a spring 27 is located and adapted to maintain the wheelI'I carried by the trolley arm, always in proper line with the conductoror trolley wire D, but at the same time permitting the depression of thetrolley arm and wheel when it is desired to move the latter away fromthe conductor by means of the usual manually operated devices on thecar.

From the construction and arrangement of parts above described, it willbe seen that the trolley carrying devices are permitted to have anoscillatory motion and yielding lateral motion and that the trolley armG is permitted to turn in the tubular arm F, thus allowing the car towhich the devices are attached to run on curves without causing thetrolley arm to bind in the slot.

The rails A constitute one of the conductors for the current, the jointsbeing connected together by a bond wire 28, said wire being held in theholes in the heads of bolts 29, by set screws 30.

Arms 31 are secured to the frame or bracket E in front and rear of thetrolley arm and project through the slot 3 for cleaning out the ice,dirt or other substance accumulating therein.

Man holes I are located at intervals of the road bed and adapted toreceive water, &c., which may pass through the slot 3. These man holesmay be connected with a sewer, as at J, for drainage purposes. Over eachmanhole a removable lid 21 is placed.

It is evident that slight changes might be made in the details ofconstruction of my invention without departing from the spirit thereofor limiting its scope and hence I do not wish to limit myself to theprecise details of construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a rail, a chair, and a slot iron comprising ahorizontal portion and two flanges depending from the edges thereof,said slot iron secured to the chair, of a trolley wire supported in thespace between the flanges of the slot iron and devices connecting theinsulator with the slot iron at three points, substantially as setforth.
